Forest fires start mostly in partial combustion. In this paper we present a hydrogen sensor to defect early stages of forest fires. First indoor experiments in a smoke density chamber with wood samples, proved that the sensor produce a strong signal change when the smouldering of wood starts, already before the CO concentration, measured in FTIR spectrometry, exceeds 10 ppm. In outdoor experiments we were able to detect forest fire in a distance of 110 m.
